In this context, Deputy Inspector General Md Ruhul Amin, who heads a probe committee, said: “Had the local administration and madrasa managing committee taken action when the sexual harassment was first reported, this tragedy could have been avoided.”

“During the investigation, we have found preliminary evidence against the former officer-in-charge of Sonagazi police station Moazzem Hossain and other senior police officers. These proofs will be submitted to the IGP immediately and necessary legal measures will be taken against the responsible officials,” he added.

Different probe committees have found negligence of the district and upazila administrations and the madrasa managing committee, according to the insiders.

According to the family of the deceased and the local civil society, the local administration failed to properly investigate the incident due to the influence of the organized gangs.

In this regard, Deputy Commissioner Mofiduzzaman said an administrative inquiry committee has been formed in this regard. “If there is any wrongdoing, necessary action will be taken,” he said.

He said the post of president of madrasa committee is ex-officio. “There are other members of the committee. Everyone will have to take the responsibility… No one will be spared.”

According to the probe committee of National Human Right Commission (NHRC), Nusrat’s murder was result of a series of negligence beginning from the time of her admission at the Alim section Sonagazi Islamia Fazil Madrasa.

Nusrat, who was an Alim examinee, suffered 80% burns when she was set on fire by four unknown burqa-clad assailants on April 6.

The assailants, who were allegedly followers of madrasa principal Sirajuddaula, took Nusrat to the roof of the institution and set her on fire.

She was attacked for refusing to withdraw a case her family filed last month against Sirajuddaula for sexually harassing and assaulting her.

After she was set on fire, her family filed another case against eight people, including Sirajuddaula, on April 8.

The 18-year-old girl died at the burn unit of Dhaka Medical College Hospital on April 10 after five days in treatment.
